The typical challenges of heavy equipment lie in discrete operating conditions, strong impact loads, and harsh service environments. Compared to passenger vehicles, heavy equipment relies more on load spectrum management and durability design than on performance optimization under a single standard operating condition.
Industry Characteristics
- Complex and highly variable off-highway operating conditions
- Welded and pinned joint areas are high-risk regions
- Customers are extremely sensitive to reliability and downtime costs
Core Tasks
- Strength verification of large structures such as booms, frames, and slewing platforms
- Dynamic load identification under impact and digging conditions
- Fatigue life assessment of welds, bearing seats, and pin-hole regions
- Coordinated analysis of hydraulic, structural, and handling stability performance
Recommended Solution
It is recommended to establish typical condition spectra based on measured data, then conduct durability analysis of critical areas using system dynamics and finite element models. For platform-based products, a condition reuse and component database should also be built to support rapid derivative designs across different tonnages and tooling configurations.
Business Benefits
The real value created by durability simulation lies in reducing prototype rework and field failures — not in making individual reports more complex.
